Development of Criteria and Test Methods for Eye and Face Protective Devices.

摘要

Eye and face protection devices required by OSHA for use by industrial employees must comply with the performance and design specifications of American National Standards Institute Standard Practice for Occupational and Educational Eye and Face Protection ANSI Z87.1-1968. Some of the requirements and test methods of Z87.1have been unchanged for many years or are not clearly defined,hence there exists a need to determine whether performance requirements are adequate and to improve test methods. Following description of a program of analytical and experimental work on three specific aspects of eye and face protection devices,recommendations are presented for significant changes in attenuation properties of light-absorptive materials such as welding plates,for a high-speed impact test employing a pointed missile,and for improved test methods for optical attributes.
